Not counting rotations, there are 4.
You can make five arrays from the number 48
You cannot sort arrays by other arrays; that wouldn't make sense, anyway.

To calculate the number of arrays that can be made out of 20 elements, we need to consider the possible combinations. Each element can either be included or excluded in the array, resulting in 2 choices for each element. Therefore, the total number of arrays that can be formed is 2^20, which equals 1,048,576.

4 (or eight if you count transposed arrays as being different).

Your question makes no sense.
By using the library function #define A[] we can define the size of arrays
One.
An array is a data type that describes a collection of ordered variables and types of arrays include vector arrays and matrix arrays.

It's actually not true. In order to make a good program which can work with big arrays you have to use dynamic arrays because you can cleam memory used by dymanic arrays any time. For static arrays is not true, memery which was reserved for static arrays will be available for other applications only when you finish working with your application (which is working with static arrays).

array is collection of many data
